Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed September 5, 1911. Serial No. 647,528.

To all whom it may concern:

Be it known that I, OTTo I-I. Boone, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Window-Guards, of which the following is'a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an improved construction of guard for windows, adapted both to prevent accidental falling through the open window and also as a protection against unauthorized entrance when the window is open for ventilation.

It consists of the elements and features of construction shown and described as indicated in the claims.

In the drawings :-Figure 1 is an inner side elevation of a window equipped with this invention. Fig. 2 is a horizontal section of the window and guard, showing the guard in process of insertion. Fig. 3 is an enlarged detail section at the line, 3,-3, on Fig. 1. Fig. 4 is an enlarged detail section at line 44.- on Fig. 1. Fig. 5 is a detail section at the line, 5,5, on Fig. 1, on an enlarged scale. Fig. 6'is a detail section at line 6-6 on Fig. 3. Fig. 7 shows a form of reinforcing escutchcon plate suitable for use in this device.

In the drawings, 1 represents the upper side bars of the window casing which is provided with sockets, 2, bored into the casing in the lower part of the run-way of the upper sash, which are furnished with reinforcing surface plates or escutcheons, 4l,4;, set in flush with the casing so as not to interfere with the running of the sash thereon. The guard device is designed to be inserted between the stops, 5,5, in the lower part of the run-way of the upper sash, and to be of such height as to make it impossible to lower the upper sash more than a few inches so that when the guard is in place, the upper sash cannot be opened enough to admit an intruder. The guard comprises two members, A. and B, each composed of two or more horizontal bars, 7, 7, only two being shown in the drawings, the number being determined by the height of the opening to be guarded, and vertical rods, 9,-9, extending through the horizontal rods and rigid therewith at their junctions. The horizontal bars, 8,-8, of the two guards are constructed to lap each other a sufficient distance so that the ends of the horizontal bars of one section are pivoted upon a vertical rod of the opposite section which is located back from the inner ends of the horizontal bars of that section a distance substantially equal to the desired interval between the consecutive vertical rods. Holes, 10,10, are provided in the horizontal bars of both sections at the position such that the said holes in the bars of one section coincide with the holes in said bars of the other section when the two sections are in line with each other, that is, in the same plane. The outer ends of the horizontalbars outside the outermost of the vertical rods, terminate in slightly curved hooks, 12, which are positioned to enter the sockets, 2, through the escutcheons or reinforcing plates, 4,4l, the curvature of the hooks being such as to adapt them to enter and to follow in through the holes in the escutchcon plates, as the two guards pivoting about their connecting vertical rod are straightened from the position shown in Fig. 2, to the closed position in which they are alined, or in the same plane. In order to render the corresponding bars, 7, of the two members, A, and I3, comparat-ively rigid with each other with respect to upward and downward bending, the lapped ends of the two bars are provided with angular rods, 21, turned upon each bar so as to engage the lapped portion of the other bar when they are alined with each other. For securing the two members, A, .B, in said closed position, there are provided two locking rods, 15 and 1.6, which together are adapted to constitute an additional vertical rod for guarding the aperture. The upper of these rods has at a short distance above its lower end an inwardlyprojeeting lug, 16, whose lower face is at right angles to the length of the rod, and on the lower rod, 15, there is mounted a sleeve, 17, having at its upper end a come sponding lug, 17, the two lugs, 16 and 17, having apertures, 16 and 17, adapted to register and receive the shackle of a pad lock,

ward or so as to 18, for securing them together. It will be observed that the sleeve, 17, when moved up to bring its lug, 17, against the lug, 16, incloses the meeting ends of the two rods, rendering them rigid as against any bending action. At the portion of the rods, 15 and 16, at which they respectively pass through the bars, 7, they are swaged to form a squared portion, 19, and immediately inward therefronn that is, below the squared portion of the upper rod and above the squared portion of the lower rod, stop flanges, 20, which stop against the bars, 7, respectively, and the holes, 10, in said bars are made square to receive said portions of the squared rods, respectively.

WVhen the two members, A and B, are brought into' closed position, that is, alined in one plane so that the square apertures, 1.0, of their respective bars coincide, the lower rod, 15, is inserted through the coinciding square apertures of the lower bars down to the shoulder, 20, and this rod has its said squared end adapted to fit quite tightly in said square apertures of the lower bars. The upper rod, 16, is then similarly inserted up through the square apertures of the upper bars, its squared end being adapted to fit a little loosely thereon so that it may be thus inserted, although necessarily deflected slightly out of line with the apertures in order to slide by the upper end of a previously inserted lower rod.

The aggregate distance at the outer surfaces of the stopped flanges or shoulders, 20, from the meeting ends of the rods, 15, and 16, respectively, is substantially the distance between the upper and lower bars, 77, of the frame, A, Whose bars fitting between the corresponding upper and lower bars of the frame, B. WVhen, therefore, the upper rod, 16, is pushed up through the square opening up to the upper bars, until it can be moved over at the lower end into line with the lower rod and the sleeve, 17, is moved up to embrace the meeting end of both rods and bring its lug, 17="-, into position for registering the apertures of the two lugs, 16 and 17, so that the pad-lock shackle can be inserted through them. The two bars are quite tightly stopped by their stop flanges, 20, between the bars, 7,7, and longitudinal movement up or down is prevented so long as the pad lock holds them engaged. With the parts in this position, it will be seen that the two members, A and B, are positively locked against folding outbe disengaged from the window casing.
